simple jquery dropdown - clearTimeout, setTimeout issues
- by user210757
HTML:
<ul class="topnav">
<li><a href="#"><span>One</span></a></li>
<li><a href="#"><span>Two</span></a></li>
<li>
<li><a href="#"><span>Three</span></a></li>
<ul class="subnav">
<li><a href="#">A</a></li>
<li><a href="#">B</a></li>
<li><a href="#">C</a></li>
</ul>
</li>
</ul>
jquery:
var timeout = null;
$(document).ready(function() {
$("ul.topnav li").mouseover(function() {
if (timeout) clearTimeout(timeout);
$(this).find("ul.subnav").slideDown('fast').show();
}).mouseout(function() {
timeout = setTimeout(closemenu, 500);
});
// sub menu mouseovers keep dropdown open
$("ul.subnav li").mouseover(function() {
if (timeout) clearTimeout(timeout);
}
).mouseout(function() {
timeout = setTimeout(closemenu, 500);
// alert(timeout);
});
// any click closes
$(document).click(closemenu);
});
// Closes all open menus
function closemenu() {
$('ul.subnav:visible').hide();
if (timeout) clearTimeout(timeout);
}
I'm having issues with timeout. In use, if i mouseover "Three", the dropdown stays out forever. if i mouseover "A", dropdown will stay out forever, but if I mouseover "B" or anything lower, the menu will close on me. if you uncomment "// alert(timeout);" it gets there for B, (and A) but timeout will have a value. why is this? i thought clearTimeout would null the timeout variable?
